Both consists of a power module soldered to driver board “The companion gate driver boards are designed to be integrated with [power] modules to provide an all-in-one motor drive solution for the electrification of systems such as flight controls, braking and landing gear for drones to all-electric aircraft,” according to the company. CD-MSCSM70XM19CTYZBNMG is rated […]
April 17, 2024 — Microchip Technology recently announced a new integrated actuation power solution that combines companion gate driver boards with our expansive Hybrid Power Drive (HPD) modules in silicon carbide or silicon technology with a power range of 5 kVA to 20 kVA. The new integrated actuation power solution maintains the same footprint regardless of the power […]
It enables small module designs with reduced component count for improved safety and electrification: high voltage interlocks, charging flaps, seatbelts, hood/trunk, gear tooth sensing, or brake-by-wire applications. For traditional safety automotive latches and switches, ranging from door and boot/trunk handles to seatbelts and brake light switches, the standard design uses a mechanical contact or […]
EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or 350W/channel into 8Ω. Bridging the two channels results in 1.4kW drive into 4 to 8Ω. Key components, per channel, are a pair of 200V […]
Consumption is 84.3μA/MHz and the company “offers a ‘software stand-by’ mode that reduces power consumption by a further 99% to 0.2 µA”, it said. Wake from this mode is in 4.6μs or less if the internal 32MHz oscillator is used. On this oscillator, Renesas said: Unlike other on-chip oscillators, it maintains precision in environments from […]
Radial flux AC motors offer some performance and packaging benefits but also bring some thermal and manufacturability issues. Part 1 of this series examined the axial-flux motor (AFM) in detail and compared it to the very widely used radial-flux motor (RFM). Part 2 of this FAQ continued the exploration of AFMs and RFMs. This final part […]
The single-channel INS1001DE is intended to supply fast powerful voltage-regulated waveforms to the gates, which are extremely sensitive to over-voltage stress. Its output pulse amplitude is set by a low-drop-out regulator using two resistors, to, for example 6V which is commonly specified for enhancement-mode GaN hemts (diagram below right). A separate internal LDO provides 5V […]
HVC 5222D with 32kbyte of flash and HVC 5422D with 64kbyte can drive brushless dc, brushed dc (2A) and stepper motors. They also have 4kbyte ram, 2kbyte of emulated eeprom and 1kbyte of non-volatile registers, and are “SEooC ASIL B ready according to ISO 26262 to support functional safety applications”, said the company. Motor-specific functions […]
The kit comes with pre-loaded configurable firmware, eliminating the need for firmware development, and replacing it with straightforward calibration and configuration through a GUI. LED lighting, especially when implemented in a highly dynamic manner, is increasingly recognized as a key element of modern automotive design. It creates striking visual differentiation, helping manufacturers to make their […]
